摘要: The present invention discloses a switching regulator control circuit which distinguishes the output short-circuit condition, imposes immediate danger, from other mild over current conditions. includes: an judgment comparing sense signal with limit to generate indication signal; time comparison clock and timer receiving signal, wherein when does not indicate short-circuit, counts first period, indicates second period shorter than for better safety protection.
